DETAILED DESCRIPTION

Arrangements and embodiments may now be described more fully with reference to the accompanying drawings, in which exemplary embodiments may be shown. Embodiments may, however, be embodied in many different forms and should not be construed as being limited to embodiments set forth herein; rather, embodiments may be provided so that this disclosure will be thorough and complete, and will fully convey the concept to those skilled in the art.

A mobile terminal may be described below with reference to the accompanying drawings. In the following description, suffixes “module” and “unit” may be given to components of the mobile terminal in consideration of only facilitation of description and do not have meanings or functions discriminated from each other.

The mobile terminal may include a cellular phone, a smart phone, a laptop computer, a digital broadcasting terminal, personal digital assistants (PDA), a portable multimedia player (PMP), a navigation system and/or so on.

FIG. 1 is a block diagram of a mobile terminal according to an embodiment. Other embodiments, configurations and arrangements may also be provided.

As shown, the mobile terminal 100 may include a wireless communication unit 110 (or radio communication unit), an audio/video (A/V) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface 170, a controller 180, and a power supply 190. The components shown in FIG. 1 may be essential parts and/or a number of components included in the mobile terminal 100 may vary. Components of the mobile terminal 100 may now be described.

The wireless communication unit 110 may include at least one module that enables radio communication between the mobile terminal 100 and a radio communication system or between the mobile terminal 100 and a network in which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include a broadcasting receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short range communication module 114 (or local area communication module), and a location information module 115 (or position information module).

The broadcasting receiving module 111 may receive broadcasting signals and/or broadcasting related information from an external broadcasting management server through a broadcasting channel. The broadcasting channel may include a satellite channel and a terrestrial channel, and the broadcasting management server may be a server that generates and transmits broadcasting signals and/or broadcasting related information or a server that receives previously created broadcasting signals and/or broadcasting related information and transmits the broadcasting signals and/or broadcasting related information to a terminal.

The broadcasting signals may include not only TV broadcasting signals, radio broadcasting signals, and data broadcasting signals but also signals in the form of a combination of a TV broadcasting signal and a radio broadcasting signal. The broadcasting related information may be information on a broadcasting channel, a broadcasting program or a broadcasting service provider, and may be provided even through a mobile communication network. In the latter case, the broadcasting related information may be received by the mobile communication module 112.

The broadcasting related information may exist in various forms. For example, the broadcasting related information may exist in the form of an electronic program guide (EPG) of a digital multimedia broadcasting (DMB) system or in the form of an electronic service guide (ESG) of a digital video broadcast-handheld (DVB-H) system.

The broadcasting receiving module 111 may receive broadcasting signals using various broadcasting systems. More particularly, the broadcasting receiving module 111 may receive digital broadcasting signals using digital broadcasting systems such as a digital multimedia broadcasting-terrestrial (DMB-T) system, a digital multimedia broadcasting-satellite (DMB-S) system, a media forward link only (MediaFLO) system, a DVB-H and integrated services digital broadcast-terrestrial (ISDB-T) systems. The broadcasting receiving module 111 may receive signals from broadcasting systems providing broadcasting signals other than the above-described digital broadcasting systems.

The broadcasting signals and/or broadcasting related information received through the broadcasting receiving module 111 may be stored in the memory 160. The mobile communication module 112 may transmit/receive a radio signal to/from at least one of a base station, an external terminal and a server on a mobile communication network. The radio signal may include a voice call signal, a video telephony call signal or data in various forms according to transmission and reception of text/multimedia messages.

The wireless Internet module 113 may correspond to a module for wireless Internet access and may be included in the mobile terminal 100 or may be externally attached to the mobile terminal 100. Wireless LA/V (WLA/V or Wi-Fi), wireless broadband (Wibro), world interoperability for microwave access (Wimax), high speed downlink packet access (HSDPA) and so on may be used as a wireless Internet technique.

The short range communication module 114 may correspond to a module for short range communication. Further, Bluetooth®, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB) and/or ZigBee® may be used as a short range communication technique.

The location information module 115 may confirm or obtain a location or a position of the mobile terminal 100. The location information module 115 may obtain position information by using a global navigation satellite system (GNSS). The GNSS is a terminology describing a radio navigation satellite system that revolves around the earth and transmits reference signals to predetermined types of radio navigation receivers such that the radio navigation receivers can determine their positions on the earth's surface or near the earth's surface. The GNSS may include a global positioning system (GPS) of the United States, Galileo of Europe, a global orbiting navigational satellite system (GLONASS) of Russia, COMPASS of China, and a quasi-zenith satellite system (QZSS) of Japan, for example.

A global positioning system (GPS) module is a representative example of the location information module 115. The GPS module may calculate information on distances between one point or object and at least three satellites and information on a time when distance information is measured and apply trigonometry to the obtained distance information to obtain three-dimensional position information on the point or object according to latitude, longitude and altitude at a predetermined time.

A method of calculating position and time information using three satellites and correcting the calculated position and time information using another satellite may also be used. Additionally, the GPS module may continuously calculate a current position in real time and calculate velocity information using the location or position information.

The A/V input unit 120 may input (or receive) an audio signal and/or a video signal. The A/V input unit 120 may include a camera 121 and a microphone 122. The camera 121 may process image frames of still images or moving images obtained by an image sensor in a video telephony mode or a photographing mode. The processed image frames may be displayed on a display 151, which may be a touch screen.

The image frames processed by the camera 121 may be stored in the memory 160 or may be transmitted to an external device through the wireless communication unit 110. The mobile terminal 100 may also include at least two cameras 121.

The microphone 122 may receive an external audio signal in a call mode, a recording mode and/or a speech recognition mode, and the microphone 122 may process the received audio signal into electric audio data. The audio data may then be converted into a form that can be transmitted to a mobile communication base station through the mobile communication module 112 and output in the call mode. The microphone 122 may employ various noise removal algorithms (or noise canceling algorithm) for removing or reducing noise generated when the external audio signal is received.

The user input unit 130 may receive input data for controlling operation of the mobile terminal 100 from a user. The user input unit 130 may include a keypad, a dome switch, a touch pad (constant voltage/capacitance), a jog wheel, a jog switch and/or so on.

The sensing unit 140 may sense a current state of the mobile terminal 100, such as an open/close state of the mobile terminal 100, a position of the mobile terminal 100, whether a user touches the mobile terminal 100, a direction of the mobile terminal 100, and acceleration/deceleration of the mobile terminal 100, and the sensing unit 140 may generate a sensing signal for controlling operation of the mobile terminal 100. For example, in an example of a slide phone, the sensing unit 140 may sense whether the slide phone is opened or closed. Further, the sensing unit 140 may sense whether the power supply 190 supplies power and/or whether the interface 170 is connected to an external device. The sensing unit 140 may also include a proximity sensor 141. The sensing unit 140 may sense a motion of the mobile terminal 100.

The output unit 150 may generate visual, auditory and/or tactile output, and the output unit 150 may include the display 151, an audio output module 152, an alarm 153 and a haptic module 154. The display 151 may display information processed by the mobile terminal 100. The display 151 may display a user interface (UI) and/or a graphic user interface (GUI) related to a telephone call when the mobile terminal 100 is in the call mode. The display 151 may also display a captured and/or received image, a UI or a GUI when the mobile terminal 100 is in the video telephony mode or the photographing mode.

The display 151 may include at least one of a liquid crystal display, a thin film transistor liquid crystal display, an organic light-emitting diode display, a flexible display and/or a three-dimensional display. The display 151 may be of a transparent type or a light transmissive type. That is, the display 151 may include a transparent display.

The transparent display may be a transparent liquid crystal display. A rear structure of the display 151 may also be of a light transmissive type. Accordingly, a user may see an object located behind the body (of the mobile terminal 100) through the transparent area of the body of the mobile terminal 100 that is occupied by the display 151.

The mobile terminal 100 may also include at least two displays 151. For example, the mobile terminal 100 may include a plurality of displays 151 that are arranged on a single face at a predetermined distance or integrated displays. The plurality of displays 151 may also be arranged on different sides.

When the display 151 and a sensor sensing touch (hereafter referred to as a touch sensor) form a layered structure that is referred to as a touch screen, the display 151 may be used as an input device in addition to an output device. The touch sensor may be in the form of a touch film, a touch sheet, and/or a touch pad, for example.

The touch sensor may convert a variation in pressure applied to a specific portion of the display 151 or a variation in capacitance generated at a specific portion of the display 151 into an electric input signal. The touch sensor may sense pressure of touch as well as position and area of the touch.

When the user applies a touch input to the touch sensor, a signal corresponding to the touch input may be transmitted to a touch controller. The touch controller may then process the signal and transmit data corresponding to the processed signal to the controller 180. Accordingly, the controller 180 may detect a touched portion of the display 151.

The proximity sensor 141 (of the sensing unit 140) may be located in an internal region of the mobile terminal 100, surrounded by the touch screen, and/or near the touch screen. The proximity sensor 141 may sense an object approaching a predetermined sensing face or an object located near the proximity sensor 141 using an electromagnetic force or infrared rays without having mechanical contact. The proximity sensor 141 may have a lifetime longer than a contact sensor and may thus have a wide application in the mobile terminal 100.

The proximity sensor 141 may include a transmission type photo-electric sensor, a direct reflection type photo-electric sensor, a mirror reflection type photo-electric sensor, a high-frequency oscillating proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and/or an infrared proximity sensor. A capacitive touch screen may be constructed such that proximity of a pointer is detected through a variation in an electric field according to the proximity of the pointer. The touch screen (touch sensor) may be classified as a proximity sensor 141.

For ease of explanation, an action of the pointer approaching the touch screen without actually touching the touch screen may be referred to as a proximity touch and an action of bringing the pointer into contact with the touch screen may be referred to as a contact touch. The proximity touch point of the pointer on the touch screen may correspond to a point of the touch screen at which the pointer is perpendicular to the touch screen.

The proximity sensor 141 may sense the proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch velocity, a proximity touch time, a proximity touch position, a proximity touch moving state, etc.). Information corresponding to the sensed proximity touch action and proximity touch pattern may then be displayed on the touch screen.

The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal receiving mode, a telephone call mode or a recording mode, a speech recognition mode and a broadcasting receiving mode. The audio output module 152 may output audio signals related to functions, such as a call signal incoming tone and a message incoming tone, performed in the mobile terminal 100. The audio output module 152 may include a receiver, a speaker, a buzzer, and/or the like. The audio output module 152 may output sounds through an earphone jack. The user may hear the sounds by connecting an earphone to the earphone jack.

The alarm 153 may output a signal for indicating generation of an event of the mobile terminal 100. For example, an alarm may be generated when receiving a call signal, receiving a message, inputting a key signal, and/or inputting a touch. The alarm 153 may also output signals in forms different from video signals or audio signals, for example, a signal for indicating generation of an event through vibration. The video signals and/or the audio signals may also be output through the display 151 or the audio output module 152.

The haptic module 154 may generate various haptic effects that the user can feel. One example of the haptic effects is vibration. An intensity and/or pattern of vibration generated by the haptic module 154 may also be controlled. For example, different vibrations may be combined and output or may be sequentially output.

The haptic module 154 may generate a variety of haptic effects including an effect of stimulus according to an arrangement of pins vertically moving against a contact skin surface, an effect of stimulus according to a jet force or sucking force of air through a jet hole or a sucking hole, an effect of stimulus of rubbing the skin, an effect of stimulus according to contact of an electrode, an effect of stimulus using an electrostatic force, and an effect according to a reproduction of cold and warmth using an element capable of absorbing or radiating heat in addition to vibrations.

The haptic module 154 may not only transmit haptic effects through direct contact but may also allow the user to feel haptic effects through a kinesthetic sense of the user's fingers or arms. The mobile terminal 100 may also include a plurality of haptic modules 154.

The memory 160 may store a program for operations of the controller 180 and/or temporarily store input/output data such as a phone book, messages, still images, and/or moving images. The memory 160 may also store data about vibrations and sounds in various patterns that are output from when a touch input is applied to the touch screen.

The memory 160 may include at least a flash memory, a hard disk type memory, a multimedia card micro type memory, a card type memory, such as SD or XD memory, a random access memory (RAM), a static RAM (SRAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), a programmable ROM (PROM) magnetic memory, a magnetic disk and/or an optical disk. The mobile terminal 100 may also operate in relation to a web storage that performs a storing function of the memory 160 on the Internet.

The interface 170 may serve as a path to external devices connected to the mobile terminal 100. The interface 170 may receive data from the external devices or power and transmit the data or power to internal components of the mobile terminal 100 or transmit data of the mobile terminal 100 to the external devices. For example, the interface 170 may include a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for connecting a device having a user identification module, an audio I/O port, a video I/O port, and/or an earphone port.

The interface 170 may also interface with a user identification module that is a chip that stores information for authenticating authority to use the mobile terminal 100. For example, the user identification module may be a user identify module (UIM), a subscriber identify module (SIM) and/or a universal subscriber identify module (USIM). An identification device (including the user identification module) may also be manufactured in the form of a smart card. Accordingly, the identification device may be connected to the mobile terminal 100 through a port of the interface 170.

The interface 170 may also be a path through which power from an external cradle is provided to the mobile terminal 100 when the mobile terminal 100 is connected to the external cradle or a path through which various command signals input by the user through the cradle are transmitted to the mobile terminal 100. The various command signals or power input from the cradle may be used as signals for confirming whether the mobile terminal 100 is correctly set in the cradle.

The controller 180 may control overall operations of the mobile terminal 100. For example, the controller 180 may perform control and processing for voice communication, data communication and/or video telephony. The controller 180 may also include a multimedia module 181 for playing multimedia. The multimedia module 181 may be included in the controller 180 or may be separated from the controller 180.

The controller 180 may perform a pattern recognition process capable of recognizing handwriting input or picture-drawing input applied to the touch screen as characters or images. The power supply 190 may receive external power and internal power and provide power required for operations of the components of the mobile terminal 100 under control of the controller 180.

According to hardware implementation, embodiments may be implemented using at least one of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, and/or electrical units for executing functions. Embodiments may be implemented by the controller 180.

According to software implementation, embodiments such as procedures or functions may be implemented with a separate software module that executes at least one function or operation. Software codes may be implemented according to a software application written in an appropriate software language. The software codes may be stored in the memory 160 and executed by the controller 180.

FIG. 2 is a detailed block diagram of the short range communication module 114 of the mobile terminal 100 according to an embodiment. With reference to FIG. 2, the short range communication module 114 may include an NFC communication module 117, a Bluetooth communication module 118, or the like.

The NFC communication module 117 may perform data communication with devices located within 10 cm (preferably, within 4 cm) by using a very short range contactless data transfer technology in relation to RFID (Radio Frequency IDentification). An electronic device adopting NFC technology may communicate with a different electronic device adopting the NFC technology through, for example, at least one of a reader mode, a card emulation mode, and a peer-to-peer mode. The NFC communication module 117 will be described in more detail with reference to FIG. 3 later.

The Bluetooth communication module 118 may perform data communication with devices present within a radius ranging from 10 m to 100 m by using Bluetooth, one of short-range wireless communication standard. For reference, Bluetooth is a short-range wireless networking technology jointly developed by a Bluetooth special interest group (SIG) organized by five companies including Ericsson, and the like, in 1998.

The block diagram illustrated in FIG. 2 merely shows an example of the short-range communication module 114 of the mobile terminal 100 according to an embodiment, and the components thereof are not essential and the short-range communication module 114 may include fewer or greater components than that illustrated in FIG. 2.

The configuration of the mobile terminal 100 according to an embodiment has been described with reference to FIGS. 1 and 2. Hereinafter, features of the mobile terminal 100 according to an embodiment capable of forming (or establishing) a plurality of communication links with different electronic devices will be described in detail.

FIG. 3 is a view illustrating a system environment including the mobile terminal 100 according to an embodiment. As illustrated in FIG. 3, it can be seen that the system environment may include the mobile terminal 100 and one or more different electronic devices 200 and 300 that may be able to form an NFC link with the mobile terminal 100.

The components of the system environment are not essential and system environment may include fewer or greater components than those illustrated in FIG. 3. Also, FIG. 3 briefly shows the components required for forming a communication link in order to largely describe the features of a formation of a communication link of the mobile terminal 100.

In FIG. 3, the system environment is implemented by the mobile terminals 100, 200, and 300, but the electronic devices 100, 200, and 300 mentioned in this document may be certain electronic devices supporting NFC communication. Namely, the electronic devices 100, 200, and 300 may be mobile terminals such as a mobile phone, a smart phone, a tablet PC, or the like, or may be electronic devices such as a printer, a TV, a DTV, a computer, audio equipment, or the like. Hereinafter, an electronic device having the NFC communication function may be referred to as an NFC electronic device.

Also, in FIG. 3, the mobile terminal 100 may form an NFC link with the different electronic devices 200 and 300 based on the NFC communication technology, a type of short-range communication technology, but the scope of the present invention is not limited thereto. For example, the mobile terminal 100 may form a wireless communication link with the different electronic devices 200 and 300 by using a short-range wireless communication technology other than the NFC communication technology.

With reference back to FIG. 3, the mobile terminal 100 includes the controller 180, the NFC communication module 117, the Bluetooth communication module 118, and the Wi-Fi communication module 119.

The controller 180 may control the components of the mobile terminal 100. The NFC communication module 117 may allow the mobile terminal 100 to form an NFC link with the different electronic devices 200 and 300 supporting NFC communication. The NFC communication module 117 may be an NFC forum device. In this document, the NFC communication module may be referred to as a short-range communication unit.

As shown in FIG. 3, the NFC communication module 117 may form an NFC link with NFC communication modules of the different electronic devices 200 and 300 through tagging within an NFC communication range.

The NFC communication module 117 may communicate with the NFC communication modules of the different electronic devices 200 and 300 in various modes. For example, the various modes may include a card emulation mode, a reader mode, and a peer-to-peer mode.

When the NFC communication module 117 operates in the card emulation mode, the NFC communication module 117 of the mobile terminal 100 may serve as a card, i.e., a tag. In this case, the NFC communication modules of the different electronic devices 200 and 300 may operate in the reader mode to obtain data from the NFC communication module 117 of the mobile terminal 100.

When the NFC communication module 117 operates in the reader mode, the NFC communication module 117 of the mobile terminal 100 may serve as a reader. In this case, the NFC communication module 117 of the mobile terminal 100 may obtain data from the NFC communication modules of the different electronic devices 200 and 300 operating in the card emulation mode.

When the NFC communication module 117 operates in the peer-to-peer mode, the NFC communication module 117 of the mobile terminal 100 and those of the different electronic devices 200 and 300 may exchange data.

The mode of the NFC communication module 117 may be determined according to a predetermined reference. For example, the mode of the NFC communication module 117 may be set according to a user input or a predetermined algorithm.

After the mobile terminal 100 forms an NFC link with the different electronic devices 200 and 300 through the NFC communication module 117, the mobile terminal 100 may form a type of communication link, different from the NFC link, with the different electronic devices 200 and 300 through the Bluetooth communication module 118 and/or the Wi-Fi communication module 119. Then, even if the NFC communication link is cut off, the mobile terminal 100 can continue to perform data communication with the different electronic devices 200 and 300 through the Bluetooth communication link and/or the Wi-Fi communication link.

In this document, the sequential process of forming a different communication link by the mobile terminal 100 with the different electronic devices 200 and 300 in order to continuously communicate with the different electronic devices 200 and 300 by using a different wireless communication technology, in the state in which the NFC links is formed, will be referred to as handover.

With reference to FIG. 3, the mobile terminal 100 according to an embodiment may know that handover can be performed from the NFC communication link to the Bluetooth communication link and the Wi-Fi communication link, but the scope of the present invention is not limited thereto. For example, the mobile terminal 100 may perform handover to various communication links such as an RFID (radio frequency identification) communication link, a WiGig (Wireless Gigabit) communication link, or the like.

Although not shown in FIG. 3, the different electronic devices 200 and 300 may include components corresponding to those of the mobile terminal 100. Namely, the different electronic devices 200 and 300 may include a controller, an NFC communication module, a Bluetooth communication module, and a Wi-Fi communication module.

In other words, handover refers to performing data communication by forming a different communication link in a state in which the mobile terminal 100 has formed an NFC link with the different electronic devices 200 and 300. Here, the user may easily form an NFC link through NFC tagging between the mobile terminal 100 and the different electronic devices 200 an 300 and change a communication means into a substitute communication link appropriate for a remote and/or high capacity data transmission, in comparison to the NFC link.

Hereinafter, a handover process of the mobile terminal 100 according to an embodiment will be described in detail with reference to the accompanying drawings. For the convenience of explanation, the system environment illustrated in FIG. 3 will be referred to. However, this is merely for the convenience of explanation and the technical concept of the present invention is not meant to be limited to a particular environment or a particular device.

FIG. 4 is a view illustrating an example of forming a communication link by the mobile terminal with the different electronic device 200 according to an embodiment. Hereinafter, the process of forming a communication link will be described with reference to the related drawings.

With reference to FIG. 4, the mobile terminal 100 may transmit a handover request message to the different electronic device 200 (S110). Before step S110, the mobile terminal 100 and the different electronic device 200 may form a communication link through a first communication unit. For example, as shown in FIG. 4, the mobile terminal 100 may form an NFC link through tagging with respect to the NFC communication module 220 included in the different electronic device 200.

With the NFC link established, the mobile terminal 100 may transmit a message for requesting handover, e.g., a handover request message, to the different electronic device 200 through the NFC link.

By transmitting the handover request message to the different electronic device 200, the mobile terminal 100 may initiate a protocol for forming a different communication link through the NFC link formed currently between the mobile terminal 100 and the different electronic device 200.

Here, the mobile terminal may be in a position of a handover requester, while the different electronic device 200 may be in a position of a handover selector. The handover requester may refer to a device initiating a handover protocol by transmitting the handover request message to the different NFC electronic device, and the handover selector may refer to an NFC device configuring a handover selection message in response to the received handover request message and making a response.

Namely, the handover requester (i.e., the handover requesting device) and the handover selector (i.e., the handover selecting device) are based on relative concepts determined whether they choose to transmit the handover request message or the handover selection message. Thus, as a matter of course, according to circumstances, when the different electronic device 200 transmits the handover request message to the mobile terminal 100, the mobile terminal 100 may become a handover selector and the different electronic device 200 may become the handover requester.

The handover request message may include information regarding a different communication module supported by the mobile terminal 100. For example, as shown in FIG. 4, when the mobile terminal 100 supports Bluetooth and Wi-Fi, the handover request message may include information regarding Bluetooth and Wi-Fi supported by the mobile terminal 100.

Communication technologies supported by the mobile terminal 100 used for handover may have determined priority. For example, as shown in FIG. 4, the handover request message may include information regarding a communication module supporting a communication technology having high priority as described at the front side and information regarding a communication module supporting a communication technology having low priority as described at the rear side. With reference to the handover request message illustrated in FIG. 4, it can be seen that the information regarding Wi-Fi communication module has higher priority than that of the information regarding the Bluetooth communication module.

Upon receiving the handover request message, the different electronic device 200 may transmit a response with respect to the handover request message to the mobile terminal 100 (S120). For example, the different electronic device 200 may generate a handover selection message as an example of a response with respect to the handover request message, and transmit the generated handover selection message to the mobile terminal 100 through the NFC link.

Here, the different electronic device 200 may analyze the handover request message to determine what kinds of communication modules are included in the mobile terminal 100, and provide information regarding a communication module included in the different electronic device 200 to the mobile terminal 100 according to the determination. Namely, the information regarding a communication module included in the handover selection message may include information regarding a communication module included in the different electronic device 200, among communication modules included in the mobile terminal 100.

With reference to FIG. 4, it can be seen that a controller 210 of the different electronic device 200 analyzes the received handover request message, determines that the Bluetooth communication module 118 and the Wi-Fi communication module 119 are included in the mobile terminal 100, and then, transmits a handover selection message including information regarding a Bluetooth communication module 230 and a Wi-Fi communication module 240 included in the different electronic device 200 to the mobile terminal 100.

When the handover selection message is received from the different electronic device 200, the controller 180 of the mobile terminal 100 may analyze the handover selection message to check that the Bluetooth communication module 230 and the Wi-Fi communication module 240 are included in the different electronic device 200, and obtain corresponding information.

Thereafter, the mobile terminal 100 forms a communication link with the communication modules included in the different electronic device 200 based on the obtained information, and then, perform data communication with the different electronic device 200 through the established communication link (S120).

For example, in order to change the NFC communication link with the different electronic device 200 to the Bluetooth communication link, the controller 180 of the mobile terminal 100 may perform Bluetooth paring with the different electronic device 200. Accordingly, the mobile terminal 100 may change the communication link with the different electronic device 200 from the NFC communication link to the Bluetooth communication link to continue to perform communication according to the Bluetooth protocol.

As the communication link between the mobile terminal 100 and the different electronic device 200 is handed over from the NFC communication link to the Bluetooth communication link, even if the mobile terminal 100 and the different electronic device 200 remain no longer within the NFC communication range, they can perform data communication and advantageously exchange data at a transfer rate faster than that of the NFC link.

In other words, when the mobile terminal 100 is a smart phone, the user may bring the smart phone to the vicinity of the different electronic device 200 and perform tagging with the different electronic device 200 to thereby form an NFC link, and perform a handover protocol to thereby change the communication unit to the Bluetooth communication link. Then, even if the user brings the smart phone to the outside of the NFC communication range, the smart phone and the different electronic device 200 may continue to perform data communication through the Bluetooth communication link.

Also, in order to change the NFC communication link with the different electronic device 200 to the Wi-Fi communication link, the controller 180 of the mobile terminal 100 may perform a process of forming a Wi-Fi communication link with the different electronic device 200 and perform data communication with the different electronic device 200 through the established Wi-Fi communication link. Then, the mobile terminal 100 may perform data communication with the different electronic device 200 at a data transmission/reception rate faster than that of the NFC communication link even at an outer side of the NFC communication range.

Here, when there are a plurality of communication links to which the NFC communication link can be changed, the controller 180 of the mobile terminal 100 may perform handover only to a communication link selected from among the plurality of communication links or may perform handover to all of the plurality of communication links. Also, when the controller 180 selects communication links to perform handover thereto from among the plurality of communication links, the controller 180 may select the communication links according to predetermined priority.

So far, the process of performing handover by the mobile terminal 100 according to an embodiment from a communication link (e.g., the NFC communication link) formed with a communication module included in the different electronic device 200 to at least one of communication links (e.g., Bluetooth communication link, Wi-Fi communication link, etc.) with a different communication module included in the different electronic device 200 has been described with reference to FIGS. 3 and 4.

FIG. 5 is a flow chart illustrating an operation of the mobile terminal according to an embodiment.

As illustrated, the controller 180 of the mobile terminal 100 according to an embodiment may determine whether or not tagging to a different device has made (S10).

Tagging may refer to an operation of bringing the mobile terminal 100 such that it is closer by more than a certain distance to the different terminal 200. The user holding the mobile terminal 100 in his hand may bring the mobile terminal 100 close to the different terminal to induce tagging. The different terminal 200 may be an electronic device available for NFC communication or a tag available for NFC communication.

When tagging is performed, a step (S20) of forming a short-range communication link may be performed.

When tagging is performed, a communication link using the short-range communication module (114 in FIG. 1) may be formed between the different terminal 200 and the mobile terminal 100. For example, an NFC communication link may be formed therebetween. When the NFC communication link is formed, data may be exchanged therethrough.

A step (S30) of obtaining tagging information through the short-range communication link may be performed.

The short-range communication link may be a communication link using the short-range communication module (114 in FIG. 1) of the mobile terminal. The short-range communication link may be an NFC communication link. When the NFC communication link is formed, data may be exchanged therethrough. Or, data may be transmitted from the different device 200 to the mobile terminal 100 through the NFC communication link.

Exchanging and/or transmission of data through the short-range communication link may be performed based on a particular short-range communication protocol. As mentioned above, short-range communication may be performed according to a scheme such as Bluetooth, Infrared ray, UWB, ZigBee, or the like. Hereinafter, it is assumed that short-range communication is performed based on an NFC scheme for the sake of explanation.

When short-range communication based on an NFC scheme is performed, the mobile terminal 100 and the different device 200 may exchange and/or transmit data according to an NDEF (NFC Data Exchange Format). Data obtained by the mobile terminal 100 according to an embodiment from the different device 200 may be a data format following the NDEF. However, required information can be added in a certain field of the NDEF.

Tagging information may be information indicating what kind of tagging it is while short-range communication based on the NFC scheme is being performed. Namely, tagging information may include information regarding an event which has occurred due to the tagging. For example, tagging information may indicate whether or not it is tagging for paying for an article (or goods), tagging for a point transmission, tagging for the use of transportation, tagging for the use of a particular service, tagging for remittance, or the like.

A step (S40) of obtaining pertinent information associated with tagging information and a step (S50) of executing a related function based on the pertinent information may be performed.

The pertinent information may be information that can be obtained based on tagging information. For example, when tagging is performed for a payment, information regarding for which article or service the payment was made may be obtained as pertinent information. This may be clearly understood from the following example. Namely, when tagging for purchasing an article is performed, information regarding whether or not there is a point, or the like, in relation to the purchase of the article may be pertinent information. The controller 180 may obtain pertinent information from an external server, or the like, based on the tagging information for purchasing the article.

Upon obtaining the pertinent information, the controller 180 may execute a related function. For example, when a point associated with a purchase of a particular article is obtained, a procedure allowing the user to check the point or use the point may be performed. The function associated with the obtained pertinent information will be described in detail in a corresponding section.

FIG. 6 is a view illustrating tagging of the mobile terminal of FIG. 5.

Tagging may refer to an operation of bringing the mobile terminal 100 such that it is closer by more than a certain distance to the different terminal 200. The user holding the mobile terminal 100 in his hand may bring the mobile terminal 100 close to the different terminal to induce tagging. The different terminal 200 may be an electronic device available for NFC communication or a tag available for NFC communication.

When tagging is performed, a communication link using the short-range communication module (114 in FIG. 1) may be formed between the different terminal 200 and the mobile terminal 1000. For example, an NFC communication link may be formed therebetween. When the NFC communication link is formed, data may be exchanged therethrough.

FIG. 7 is a view illustrating a signal flow between the mobile terminal, the different terminal, and a wireless Internet server according to an embodiment.

As illustrated, the mobile terminal 100 according to an embodiment may be tagged to the different terminal 200 (S10).

When the mobile terminal 100 is tagged to the different terminal 200, a step (S12) of forming a short-range communication link may be performed. Namely, for example, an NFC communication link may be established.

When the short-range communication link is formed, link data may be transmitted from the different terminal 200 to the mobile terminal 100 (S13). The link data may be data required for handover.

The mobile terminal 100 may transmit the link data to the wireless Internet server 300 (S14), based on which a wireless Internet link may be formed (S15).

The wireless Internet server 300 may be a different electronic device having a management attribute with respect to communication using the wireless Internet. The wireless Internet server 300 may communicate with the mobile terminal 100 through an AP (Access Point).

By transmitting the link data, a wireless Internet link may be formed between the mobile terminal 100 and the wireless Internet server 300. Namely, handover may be performed from the short-range communication link to the wireless Internet link.

The controller 180 may obtain tagging information and/or pertinent information by using the short-range communication link and/or the wireless Internet link formed by tagging. Namely, for example, tagging information may be obtained through the short-range communication link and the pertinent information may be obtained through the wireless Internet link. In this case, the pertinent information which may be large in volume can be easily obtained through the wireless Internet link.

As shown in FIG. 12( b), the mobile terminal 100 may be brought into contact with the different mobile terminal 200 (or the mobile terminal 100 may be allowed to collide with the different mobile terminal 200). When the mobile terminal 100 is brought into contact with the different mobile terminal 200, coupons collected in the mobile terminal 100 may move to the different mobile terminal 200.

The mobile terminal 100 and the different mobile terminal 200 may exchange information by using a short-range communication method including NFC. For example, when the mobile terminal 100 and the different mobile terminal 200 approach, a short-range communication link may be generated by using NFC communication, and then, a next operation may be on standby. When the mobile terminal 100 is brought into contact with the different mobile terminal 200, the controller 180 may determine which of them has been moved to be brought into contact based on sensing results through an acceleration sensor, or the like, of the mobile terminal 100 and/or the different mobile terminal 200. Thus, based on the contact results, the controller 180 may determine a direction in which the coupons are to be transmitted.

As shown in FIG. 13( a), when payment is made through tagging using the NFC scheme, the controller 180 may display corresponding information on the display 151. In addition, coupon information as pertinent information may be displayed as mentioned above.
